Wireless Fluxuation Please Help

I have just recently started useing a wireless network and while not new to computers am a definate beginer to wireless. I purchased the Belkin F5D7321-4 802.11g router and the Belkin F5D7001 card to go with it and am running WinXP. I managed to set it all up and while it works it seems like the connection is intermitant. I've been surfing around trying various recomendations to improve the stability and while I now have a stronger signal I still have long pauses in my connection. (Even when comunicating with the router when chaging settings) Nothing I do seems to really improve the situation. I get a signal can see the net and at times can surf and DL like its supposed to, then immeidatly flip over to not being able to send or can send but not recieve or completly drop connection to the wireless net. Speed tests from DSLreports.com are all over the board 1199/628, 211/16, 758/1012, 977/411 dl/ul .. I have no idea what to do to even try and stabalize this. I've tried lowering the network speed, no differance, tried changing to 802.11b no difference, tried every channel available. Are there any internal settings that can be changed to govern the responce time and speed of transmitions over the network? Or is this some thing that cannot be solved by setting and an indication that I should go buy a LONG peice of cat5 cable?

Good suggestion. I'd also make sure you don't have an outdated firmware on the router/AP. You might also try to setup WEP if you haven't or remove it if you have. One of your symptoms sounds like a WEP conflict.
